Strong artifacts caused by patient motion during MR scans affect image quality and clinical evaluation. In this work, we propose a novel motion correction framework for free-breathing cardiac MRI with multiple single-shot Late Gadolinium Enhancement data acquisition. The resulting motion-corrected image is recovered through an advanced reconstruction scheme which incorporates a non-rigid registration. The performance and effectiveness of our model was tested off-line through simulation studies. Results achieved by the present technique show significant reduction in blurring artifacts while exhibiting sharper geometric features. This technique holds potential for achieving higher quality LGE images in challenging patient populations compared to conventional methods.
